Analysis of Dust Transport Event via Remote Sensing and Numerical Forecast Model

Year 2014, Volume: 23 Issue: 2, 53 - 64, 01.12.2014

Abstract

Dust transports from African deserts cause an intense increase of aerosol concentrations in the tropospheric column and often an increase of particulate matter (PM10) at the ground level. For this reason, they have an important impact on Mediterranean site. The area was selected as the Sahara desert and the eastern Mediterranean, where an intense dust event occurred during the period 6–8 April 2013. As the first step, synoptic analysis of this episode is performed for the period of 7–8 April 2013. Synoptic analysis and satellite based model forecasts showed the Egyptian deserts as dust source region. Dust plumes hovered off the coasts of Egypt on April 7 and spanned Cyprus and the sea’s eastern shoreline the following day, reaching as far north as Turkey. The NMMB/BSC-Dust model captured these high values as good matched with the MODIS on NASA’s Aqua satellite. It was observed that the NMMB/BSC-Dust model produces well predictions for dust transport and can be used for early warnings in Turkey.

TOZ TAŞINIMI OLAYININ UZAKTAN ALGILAMA VE SAYISAL TAHMİN MODELİ İLE ANALİZİ

Year 2014, Volume: 23 Issue: 2, 53 - 64, 01.12.2014

Abstract

Afrika çöllerinde gerçekleşen toz taşınımları, atmosfer aerosol konsantrasyonunda ve yer seviyesi partikül madde (PM10) değerlerinde yoğun artışa sebep olmaktadırlar. Bu nedenle Afrika kaynaklı toz taşınımları, Akdeniz üzerinde önemli etkilere sahiptirler. Bu çalışmada, 6-8 Nisan 2013 döneminde Afrika üzerinden Doğu Akdeniz’e doğru gerçekleşen toz taşınım olayı incelenmiştir. İlk adım olarak, 7-8 Nisan 2013 dönemi sinoptik açıdan analiz edilmiştir. Yapılan sinoptik analizler ve uydu gözlemlerine dayanan model sonuçları, toz taşınımının kaynak alanının Mısır çölleri olduğunu göstermiştir. Mısır üzerinden hareketlenen çöl tozları, Kıbrıs ve Akdeniz’in doğu kıyılarını süpürerek kaynak sahasından ayrıldıktan bir gün sonra Türkiye’nin kuzeyine ulaşmıştır. Tahmin modeli çıktıları bu toz taşınım olayını saptamış ve NASA’nın MODIS/Aqua uydusu ile de iyi eşleşme göstermiştir. NMMB/BSC-Dust tahmin modelinin, toz taşınımı için iyi tahmin ürettiği ve ülkemiz açısından erken uyarılarda kullanılabileceği görülmektedir.

Anahtar Kelimeler: çöl tozu,  atmosferik taşınım, toz modellemesi, uydu aerosol verisi
